- ✓ Current: up to 342 A
- ✓ Power: up to 225 kW
Programmable Bidirectional DC Power Supply With Integrated Regenerative DC Load
The KEWELL S7200 Series combines a programmable bidirectional DC power supply with a regenerative electronic DC load. It is designed for test applications where power, voltage, energy flow, and dynamic load changes need to be controlled precisely. The series can operate as a DC source or DC load and supports CV, CC, CP, and CR operating modes.
Bidirectional Source/Sink Operation for Dynamic Test Applications
The KEWELL S7200 Series supports precise charging, regenerative energy feedback, and the generation of complex signals, waveforms, and user-defined profiles. This enables realistic and repeatable test sequences for laboratory, development, test field, and quality assurance applications. Battery simulation and bidirectional charging further extend the range of applications. Software for automation and documentation supports integration into test workflows; optional interfaces such as GPIB provide additional integration options.
NG and PG Models for Different Test Requirements
The NG models are designed as universal bidirectional source/load systems and are particularly suitable for test applications in photovoltaics, e-mobility, and power electronics as well as laboratory and test field environments. The PG models extend this functionality with specialized battery test functions and corresponding options for detailed energy storage characterization. These include the “Automotive Power Curve” function. Applications in power grids and energy storage systems can also be covered.
Alternative Products:
For applications in a comparable power range, the Kewell S7000-H Series is an alternative. It is available in several power ratings starting at 7.5 kW, but provides a lower maximum voltage and lower output current than the KEWELL S7200 Series. For higher-power and scalable test systems, the dual-channel ITECH IT6600C Series provides 42 kW per unit and can be expanded into the megawatt range.
